BUBBLE PIPE.

Application filed October 23, 1926.

The present invention relates to improvments in devices for use particularly in the formation vof soap bubbles, although the invention is not confined to such use but may be employed for many similar purposes and will lind utility in other arts, such as glass blowing.

The object of the invention is to provide a device of this class which is in the form of 1U a pipe and provided with means for increasing` the adhesion between the bubble and the erfd of the pipe whereby the formation of bubbles of the size desired is facilitated.

vWith this end in view, the extremity of the pipe is constructed with a number lof longitudinally extending slits arranged around the circumference thereof and the frayed ends thus formed are bent outwardly at angles to the axis of the pipe, thus prozo viding a large surface to which the bubble may adhere and a construction which is simple, cheap and effective in service.

For a more complete understanding of the invention, reference will now be had to the accompanying drawings forming a part of this specification, which disclose the preferred form of the invention, and in which Figure l is a longitudinal VView of the device; showing the manner of forming a bubble; c

Figure 2 is a similar view without the bubble;

Figure 3 is an end view, showing the nat-ure of the frayed ends. i

Referring now to the drawings, the device disclosed embodies a long slender pipe, `10, of aluminum or similar material by means 0f which the bubbles are adapted to be blown in a well-known manner. The extremity of the pipe on which the bubbles are formed is frayed to form prongs, l1, extending at Serial No. 143,561.

acute angles to the axis of the pipe. These prongs are preferably formed by slitting the extremity of the pipe longitudinally (as by means of snips kor the like)v at a plurality of points around its circumference and the frayed ends are then bent outwardly. The prongs so lformed provide a large adhesive surface for the bubbles, thus resulting in a' construction whereby bubbles of the desired size may be easily blown. f

It will benoted that the above construction is very simple and the device so made can be manufactured Aand sold cheaply. Although of great simplicity and low cest, it is withal very effective when used for the purpose designated. The divergence of the prongs may be adjusted simply bybending them and thus the optimum divergence of said prongs may be determined. This will perhaps vary to some extent depending on the size of bubble desired, although the angles of the prongs with the axis of the pipe should never reach or exceed ninety degrees and for lthe most part angles of about forty-five degrees will be found satisfactory. Although I have described a specific embodiment of the invention, Ido not desire to be limited thereto as various slight changes and modifications may be made therein within the spirit and scope of the invention and of the appended claim.

I claim:

A device for blowing bubbles comprising a pipe having at one extremity a plurality of longitudinal slits disposed circumferentially and forming frayed ends, said frayed ends being bent outwardly into prongs.

In testimony whereof, I have signed 1n name to this specification this 19th day of October, 1926.
